Making and Burning DVDs with Growisofs

Using the growisofs command, you can combine the two steps of gathering files into an ISO image (mkisofs) and burning that image to DVD (cdrecord). Besides saving a step, the growisofs command also offers the advantage of keeping a session open by default until you close it, so you don’t need to do anything special for multi-burn sessions.

Here is an example of some growisofs commands for a multi-burn session:
$ growisofs -Z /dev/dvd -R -J /home/chris Master and burn to DVD
$ growisofs -Z /dev/dvd -R -J /home/francois Add to burn
$ growisofs -M /dev/dvd=/dev/zero Close burn

If you want to add options when creating the ISO image, you can simply add mkisofs options to the command line. If you want to burn a DVD image using growisofs, you can use the -dvd-compat option. Here’s an example:
$ growisofs -dvd-compat -Z /dev/dvd=image.iso Burn an ISO image to DVD

Create a Virtual File System

If you want to try out different file system types or simply make a file system that is more portable (in other words, not tied to a physical disk), you can create a virtual file system. A virtual file system is one that sits within a file on an existing file system. You can format it as any file system type you like, move it around, and use it from different computers.

Virtual file systems are useful for such things as creating live CDs or running dedicated virtual operating systems. In the example that follows, you create a blank 500MB disk image file, format it as a file system,

How OpenSSH Works

When OpenSSH starts, it first establishes an encrypted connection and then authenticates the user. Once these two tasks are completed, OpenSSH allows the two systems to send information back and forth. OpenSSH uses two key pairs to negotiate an encrypted session: a host key pair and a session key pair. The host key pair is a set of public/private keys that is established when you install the openssh-server package

The first time an OpenSSH client connects with an OpenSSH server, you are asked to verify that it is connected to the correct server. After verification, the client makes a copy of the server’s public host key. On subsequent connections, the client compares the key provided by the server with the original key it stored. Although this test is not foolproof, the next one is quite secure

The client then generates a random key, which it encrypts with both the server’s public host key and the session key. The client sends this encrypted key to the server. The server, in turn, uses its private keys to decrypt the encrypted key. This process creates a key that is known only to the client and the server and is used to encrypt the rest of the session
